The laser head nozzle is a commonly used consumable part on the laser pipe cutting machine. With the acceleration of the industrialization process, the development and wide application of the laser tube cutting technology, the demand for the laser head nozzle has increased significantly in recent years. Let us briefly talk about the laser nozzle. Several important roles in laser pipe cutting machines:
The first is to collect the capacitive signal and transmit it to the signal processor through the ceramic ring. The signal processor sends a signal to the machine control center. The machine control center feeds back according to the signal and adjusts the position of the laser in the vertical direction to keep the tracking laser head in place. The distance from the workpiece during the cutting process.
The second is to use its internal shape to direct the gas through the cut workpiece and create a high pressure at the nozzle outlet attachment. The smaller the nozzle outlet orifice, the higher the pressure generated. The higher the pressure generated, the higher pressure oxygen passes through the nozzle in the case of oxygen cutting, and part of the working surface is oxidized by the same cutting member to provide heat to accelerate the cutting, and the other portion passes through the cutting surface at high speed, carrying the slag and the cutting surface. Maintain proper shape and pressure to ensure smooth cutting.
The third is to protect the internal lens of the laser head. During the cutting process of the laser pipe cutting machine, especially when punching, the slag is often sputtered. The high-pressure gas blown by the laser head nozzle can block most of the sputter material and protect the lens from the lens. damage.
